This paper questions our incapacity to think out social relations beyond law and law systems. Why is it that justice must necessarily be attained by means of law? Even when feminist criticism of law adopts postmodernist ways such as in Drucilla Cornell's work, it nevertheless leads to the unavoidability of law. Or else to a juridico-political pessimism, as found in MacKinnon's work. Examining the feminist justification for resorting to law through the analysis of the Legal Education and Action Fund's intervention before the Supreme Court of Canada on the question of obscenity in the Butler case, it is argued that the judicial system stays shut to differance, to otherness, and, therefore, to justice.
